Schwarzchild radius is event horizon size of non-rotating black hole. Objects inside cannot escape, even light.

  1. 1Input mass (solar masses or kg)
  2. 2Apply r_s = 2GM/c²
  3. 3Results show black hole horizon size

Worked Examples

Инпут
M = 10 solar masses
Резултат
r_s ≈ 30 km, density ≈10¹¹ kg/m³
Stellar-mass black hole

Common Mistakes to Avoid

  • Assuming black holes are absolute sinks (Hawking radiation evaporates)
  • Neglecting spin (rotating black holes larger)

Frequently Asked Questions

What happens at event horizon?

Tidal forces increase dramatically; approaching observer experiences infinite time dilation.
